PAD LOCK.

SPECIFICATION forming part of Letters Patent No. 415,187, dated November 19, 1889.

Application filed June 21, 1889. Serial No. 315,047. (No model.)

To all whom it may concern:

Be it known that I, \VILLIAM F. BEASLEY, a citizen of the United States, residing at Oxford, in the county of Granville and State of North Carolina, have invented certain new and useful Improvements in Locks; and I do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to locks, but has special reference to the construction of the shackle of a padlock, and has for its object to so construct said shackle that it cannot be bent to one side to release the usual staple without destroying the shackle.

In register-locks, especially such as are commonly used by the United States Government, the main feature is the registering mechanism, while the lock itself is not considered of much importance, and is therefore of a very simple and ordinary construction. In such locks the safety resides in the fact that in order to release the staple which is engaged by the shackle the latter must be raised or turned to one side, thereby causing such lock to register and thus afford a tellcan be effected in the instance of any opennosed shackle, or, in other words, any shackle which does not lock at the nose, and it is the sole aim of this invention to overcome this defect.

In the accompanying drawings, Figure 1 is an elevation of a lock having a shackle constructed in accordance with my invention; Fig. 2, a plan of the same, and Fig. 3 a modification of my invention.

Similar letters denote like parts in the sev eral figures.

A is the lock-casing; B, the shackle, and the shackle-stump.

D are notches cut in the sides of the shackle to impair its strength, so that any attempt to bend said shackle will result in breaking or cracking the same, thus affording a means for the detection of such attempt. Holes E may be bored through the shackle, as seen at Fig. 3, instead of cutting the notches, the gist of my invention resting in the broad idea of cutting away at various points the stock of the shackle.

Having thus described my invention, what I claim as new, and desire to secure by Iietters Patent, is

1. In a padlock, the shackle having its stock cut away at various points, substantially as set forth.

2. The open -nosed shackle having cut therein notches, substantially as set forth.

In testimony whereof Iaffix my signature in presence of two witnesses.
